If your PNG image shows transparency with
Gui, Add, Picture
then it should be displayed correctly with GDI+

I have created a dll file using your Rod-Ex program:

http://www.autohotkey.com/forum/topic30228.html

it contains all png files except 9012 which is a jpg

I can not get any of them to display. Here is my code - i created a loop to display all the images so that i knew which was which:




Code:
Gui, Margin, 0, 0
resfile:=A_ScriptDir . "\resource.dll"
rescount:=9000
maxres:=9013
hModule   := DllCall( "GetModuleHandle", Str, resfile )
loop
{
   if (rescount>=maxres)
      break
hResource := DllCall("FindResource", UInt,hModule, UInt,rescount, UInt,10)
;msgbox,,, hresource%rescount% : %errorlevel%,.5
nSize     := DllCall("SizeofResource", UInt,hModule, UInt, hResource)
;msgbox,,, nsize : %errorlevel%,.5
hResData  := DllCall("LoadResource", UInt,hModule, UInt,hResource )
;msgbox,,, hresdata : %errorlevel%,.5
Buffer    := DllCall("LockResource", UInt, hResData )
;msgbox,,, buffer : %errorlevel%,.5
; Converting Image data to hBITMAP ; Thanks Sean
; http://www.autohotkey.com/forum/viewtopic.php?t=22999

hData := DllCall("GlobalAlloc", UInt,2, UInt, nSize )
;msgbox,,, hdata : %errorlevel%,.5
pData := DllCall("GlobalLock",  UInt,hData )
;msgbox,,, pdata : %errorlevel%,.5
DllCall( "RtlMoveMemory", UInt,pData, UInt,Buffer, UInt,nSize )
;msgbox,,, rtlmovememory : %errorlevel%,.5
DllCall( "GlobalUnlock", UInt,hData )
;msgbox,,, globalunlock : %errorlevel%,.5
DllCall( "ole32\CreateStreamOnHGlobal", UInt,hData, Int,True, UIntP,pStream )
;msgbox,,, ole32 : %errorlevel%,.5
DllCall( "LoadLibrary", Str,"gdiplus" )
;msgbox,,, loadlibrary : %errorlevel%,.5
VarSetCapacity(si, 16, 0), si := Chr(1)
DllCall( "gdiplus\GdiplusStartup", UIntP,pToken, UInt,&si, UInt,0 )
;msgbox,,, gdiplusstartup : %errorlevel%,.5

DllCall( "gdiplus\GdipCreateBitmapFromStream", UInt,pStream, UIntP,pBitmap )
;msgbox,,, gdipluscreatebitmap : %errorlevel%,.5
DllCall( "gdiplus\GdipCreateHBITMAPFromBitmap", UInt,pBitmap, UIntP,hBitmap, UInt,0 )
;msgbox,,, gdipluscreatebitmapfrombitmap : %errorlevel%,.5
pichandlename:="pic" . rescount
gui,add,text,,%rescount%
Gui, Add, Text, +0xE hWnd%Pichandlename% ; +0xE is SS_BITMAP
pichandle:=%pichandlename%
SendMessage, (STM_SETIMAGE:=0x172), (IMAGE_BITMAP:=0x0), hBitmap,, ahk_id %Pichandle%
msgbox ,,,pichandle:%pichandle%.%pichandlename%.%rescount%,3
rescount++
}
Gui, Show,h600 w1000, SoggyDog
;msgbox pauseing

DllCall( "gdiplus\GdipDisposeImage", UInt,pBitmap )
DllCall( "gdiplus\GdiplusShutdown", UInt,pToken )
DllCall( NumGet(NumGet(1*pStream)+8 ), UInt,pStream )
Return         

GuiClose:
GuiEscape:
 ExitApp
Return


here is a link to my resource.dll : http://www.mediafire.com/?4zsmv9eyljj

However, when I embed the same images into the exe, they do display, which must mean something is wrong with the dll?

Nothing wrong with the DLL!

Replace
hModule := DllCall( "GetModuleHandle", Str, resfile )
with
hModule := DllCall( "LoadLibrary", Str, resfile )

Some info:

  • To access functions or resources from DLL, The DLL needs to be loaded into memory and an handle to it needs to be obtained.
  • System DLL's like Kernel32.dll are preloaded by Windows and so we need not load the library, just use GetModuleHandle() to obtain a handle to it.
    Same goes for Compiled AutoHotkey Script, where you obtain ModuleHandle of the running executable.
  • To access the resources of a resource.dll, you need to load the DLL first,
    So we can load it by callling LoadLibrary().
  • In this particular case of Resource.dll, it does not have a DllMain routine ( which is something like an Auto-Execute section of a DLL ), so we can call LoadLibrary() safely.
    But generally speaking, it is best to call LoadLibraryEx() which can load the dll without executing the DllMain()
    Code:
    hModule := DllCall( "LoadLibraryEx", Str,"resource.dll", UInt,0, UInt,0x2 )



On more thing. You are Starting and Shutting down GDI+ on every iteration of loop. Start GDI+ with script and shut-it down on exit.
Refer the following post which shows a better way of handling resource images
Creating a JPEG only DLL and retrieving the images

One more thing.

I want to load bitmaps in, but not display them. I want to use them with imagesearch, but would still like them to be in the dll file.

how do I reference them from the dll using image search?

ImageSearch will not work with GDI bitmap handles..
At the most you can use Icon resources with ImageSearch

Once you obtain the hbitmap using GDI+, use CopyImage() to copy it to a different size, Delete the old hBitmap, use STM_SETIMAGE with the new hBitmap

Code:
New_hBitmap := DllCall("CopyImage",UInt, Old_hBitmap,UInt,0,Int,640,Int,480, UInt,0)
